IMPROVEMENT IN'MACHINES FOR FEEDING, PASTING, AND CUTTINGPAPER AND OTHER FABRICS.

Specification forming part of Letters Patent No. 200,307, dated February 12, 1878 application filed January 12,1878.

To all whom it may concern.-

Be it knowngthat I, GUSTAV L. J ALEGER, of the city, county, and State of New York, have invented a new and useful Improvement in Machines for Feeding, Pasting, and Cutting Paper and other material, which improvement is fully set forth in the following'specification, reference being had to the accompanying drawing, in which- Figure 1 represents a side view. Fig. 2 is a longitudinal vertical section. Fig. 3 is aplan or'top. view. The remaining figures are details, which will be referred to as the description progresses."

Similar letters indicate corresponding parts.

This invention relates to a machine for feeding, pasting, and cutting paper and other inaterial, in which the paste-roller works directly in the paste-trough, and is adapted to be moved toward and from the cylinder which carries the web to be supplied with paste, so that it can at any moment be thrown out of contact with the web or the web-carryin g cylinder, the lever which serves to move the pasteroller being so arranged that it locks said paste-roller in the required'position.

When paste is to be applied to two webs at the same time, the paste-rollers are connected to rock-shafts, which receive motion by'a single hand-lever, the position of which is deter mined by a notched plate. A-yielding scraper, which is held in contact with the paste-roller by a weight or spring, serves to regulate the quantity of paste to be transmitted to the web. The paste -'rollers work in troughs situated one above the other, and with these paste-- troughs is combined an automatic. paste-feed' ing mechanism. The pasteboards to be lined are fed to the machine by a slide, which receives its motion from the shaft of a revolving cutter that serves to separate the webs between the succeedingsheets of pasteboard, the motion of the cutter being made adjustable for sheets of different length. A brush, which is also moved from the cutter-shaft, senves to press down the ends 'of the webs after the same have been cut. The roll which contains the web is placed on two ro1lers,'with or with-" out an'endless apron, for the purpose of facili tatin g the operation of- "drawin g off the web. With these supporting-rollers is combineda trough containing water or other liquid, so as to moisten the web as the same is drawn on from the roll.

In the drawing, the letter A designates" a frame, which forms the bearings for the compression-c'ylinders B B, the paste-rollers O G, and of all the remaining working'parts of my machine. In this frame is firmly secured a table, D, over which the, pasteboard is fed to the compression-cylinders B B. These cylin ders are held in contact with each other by springs a, Fig. 1', and they are geared together so that they revolve in the direction of the ar rows shown thereon in"Fig. 2.

In the example shown in the drawing the pasteboard is fed into the machinein sheets; but it may be fed from a roll the same as the paper.

The paper or other material which serves to" line the pasteboard simultaneously on both sides is taken from rolls E E, and as the same is carried round the cylinders to their point of contact it i'sdrawn off automatically by the gripe of said cylinders, and at the same time bothwebs are supplied with paste by the action of the paste-rollers G 0 before they reach the point of contact of the cylinders. These paste-rollers run" directly in the paste-troughs F F, and they are geared together with the cylinders "B B, so that they revolve with the same circumferential velocity, or nearly so. With the paste-rollers is combined a suitable mechanism for moving the same at'any moment away from their cylinders or up to the same, as maybe requisite. The mechanism which serves tocontrol the position of the paste-roller'G consists of arock-shaft, f, on which are firmly mounted two arms, '01, one on each end and these arms are provided with holes to receivethe shaft b of the paste-roller (l. When the rock-shaft f is turned inthe proper direction, said paste-roller is raised out of its paste-trough, and atthe sametim'e moved out of contact with the cylinder B. The mechanism which serves to controlthepositionof the paste-roller 0 consists of'arock-shait, f onthe ends of which are firmly mounted two cranks, 6, each of which is pivoted to one end of a strap, d, the opposite end of which is bored out to receive the shaft b of the paste-roller O. On

.nd by moving this hand-lever to the position hown in dotted lines in Fig. l the paste-roller l is caused to slide back in its bearings, so hat it revolves out of contact with the cylinler B. The two rock-shafts ff 1 are connected vy a rod, h, which is attached to one of the .rms d by a pivot, g, and to one of the cranks 1 by a pivot, g, so that by means of the handaver t the position of both paste rollers can be ontrolled. This lever engages with notches j, in the edge of a plate, Ir, which is secured o the table D by screws 1, passing through lots m, so that the same can be moved tovard and from the cylinders B B. When the land-lever is thrown in gear with the notch j, 10th paste-rollers are brought in contact with heir respective cylinders, and retained in this )osition, and by throwing the hand-lever in gear with the notch j both paste-rollers are moved away from their cylinders, so that no )aste is applied to the webs or to the surfaces f the cylinders in case the webs (or one of hem) should have given out. By adjusting he plate 70 the pressure exerted by the paste- 'ollers against the cylinders can be regulated ,o suit circumstances. The paste-troughs F F, from which the paste-rolls take their paste, tre situated one above the other, and the up- )er trough F is provided with an overflow- )ipe, 42, Figs. 2 and 4, which extends down nto the lower trough. The upper trough is mpplied with paste through a feed-pipe, 0, which connects with a suitable supply-tank, tnd with the discharge-opening of this feedpipe is combined a valve, 19, which connects 9y a rod, q, with a float, 'r, situated in the .ower trough. As the paste rises in the upper trough to a level with the mouth of the overflow-pipe n, it discharges into the lower trough until the float r rises to such a height that the valve 19 is closed. As the paste is consumed the float sinks down, the valve 1) opens, and a fresh supply is admitted.

By this arrangement both troughs are automatically supplied with paste, and no personal attention is required to this portion of the work.

With each of the paste-rollers O G is combined a doctor or scraper, s, (one only being shown in the drawin g,) which consists of a strip of india-rubber or other equivalent flexible material, secured in an arm mounted on a rockshaft, t, from which extends an inclined arm,-u, which carries an adjustable weight, 0;, so that by the action of this weight the scraper is held in contact with the paste-roller, and by adjusting the weight the pressure of the scraper on the surface of the paste-roller can be regulated, and thereby the quantity of paste transmitted to the web can be controlled.

In the example represented by the drawing a machine is shown in which the pasteboard to be lined is fed into the machine in the form of sheets. The mechanism for feeding the sheets consists of a slide, G, which rests on the table D, and is guided by a pm, a extending through a slot, 1)", Fig. 2. A spring, 0 forces the slide back to the position shown in dotted lines in Figs. 1 and 3. The forward motion of this feed-slide is produced by arod,

d, which is attached to it by a screw, 0 extending through a slot, f so that it can be adjusted for sheets of difl'erent length. On the outer end of this rod is a nose, g, Figs. 1 and 7, which is acted on by a cam,h mounted on the knife-shaft F. This shaft is geared together with the upper cylinder B by cogwheels 70 1 so that it revolves in the same direction as said cylinder, and by the action of the cam h on the nose g the slide G is drawn into the position shown in Figs. 1 and 2. so that a sheet of pasteboard placed on said slide is delivered to the cylinders between-the two webs which extend partially round said cylinders. As soon as the cam h has passed the nose 9 the slide G flies back to its original position, while the sheet of pasteboard which has been delivered to the cylinders B B is carried forward between these cylinders, and the two webs which have been supplied with paste, as previously described, being pressed against the sheet of pasteboard from opposite sides, are caused to adhere to the same.

The knife mtis secured to the shaft '5 and it co-operates with a stationary cutting-edge, 12 Its motion is so regulated that it' acts upon the two webs close behind the sheet of pasteboard to which said webs have been pasted, and the sheets of pasteboard are fed to the machine, so as to leave a small space (see Fig. 2) between the succeeding sheets, allowing the knife to separate the two webs.

In order to adjust my machine to sheets of diflerent length, the cog-wheel l is secured to an adjustable bracket, 0 and the cog-wheel k on the knife-shaft is fastened by a setscrew or other means, so that the same can be readily removed and replaced by another of difl'erent diameter.

If the speed of the knife is reduced, the feedslide G has to be set back for sheets of greater length, and vice versa. Instead of the gearwheels Z 70 any other suitable mechanism can be substituted for re gulatin gthe relative speed of the knife-shaft.

After the webs have been cut, their ends are liable to become detached from the outer which is connected to'a rod, 1:, which is sub jected to the action of a spring, v and provided with a nose, against which the cam q acts. By the action of the cam the brush is moved from the position shown in dotted lines in Fig. 2 to that shown in full lines, and thereby the ends ,of the webs are presseddown; on the pasteboard. As soon as the cam has passed-the nose of the rod t the brush returns to the position shown in dotted lines bythe action of the spring v Instead of using a vibrating brush for this purpose, a revolving brush might be used, and the motion of this brush may be produced by cog-wheels or any other suitable means.

An endless apron, H, serves to discharge the finished sheets at the rear end of the machine.

The rolls E E from which the webs are taken may be of different nature. In the example shown in the drawing the roll E is provided with gudgeons, which have their bearings in the main frame; but the roll E, which has no gudgeons, is placed on an endless apron, I, Fig. 2, which extends over rollers 0. b and receives its motion from the lower cylinder B. (See Fig. 1.)

In the frame A are secured two disks, 0 the stems d of which are adjustable in their bearings by set-screws 6 Fig. 1, so that the distance between the disks can be adjusted to conform to the width of the roll E. The roller 11 is in close proximity to the cylinder B, so that the web is grasped between the apron I and said cylinder, and as the cylinder revolves a slow rotating motion is imparted to the roll E, and the web is readily drawn off. With the apron I is combined a roller, f which dips into a trough, 9 containing water, so that the apron is supplied with moisture and the web resting thereon is moistened as the same is drawn off. This arrangement is desirable when paper is used that is very hard and stiff. The endless apron I may, however be omitted, and the roll E placed directly upon the rollers a 11 said rollers being made sufficiently large for the desired purpose. The moistening-rollerf may also be omitted and the roller a so placed that it dips into the liquid contained in the trough g, for the purpose of moistening the web composing the roll E.

The cylinders B B may be used with or without gripers 11. and in order to be able to use the cylinders either way, I have arranged the griper h in a cavity in the cylinder, which is covered by a protecting-plate, i the face of the griper and that of the protecting=plate being so formed that when the griper is closed the surface of the cylinder towhich the same is applied remains unbroken, as shown in Figs. 2 and 5.

By means of the gripers, the end of the web can be readily secured to the cylinder and drawn off from the roll without difficulty, so as to carry the same round the cylinder in the proper position when the machine is first started. Asthe pasting operation progresses the gripers are not required.

If desired, the gripers may be made to catch over the edges of the web from opposite sides,

the protecting-plate i may be made separate from the cylinder and attached to it in the proper position, or the cavity containing vthe What I claim as new, and desire to secure by Letters Patent, is; v 1.
